Earlier this year, Whoop introduced a stress tracking feature. Now, they’ve taken this a step further. The latest update in the smartphone app introduces Total Day Stress, Non-Activity Stress, and Sleep Stress, offering users a more comprehensive view of this metric.

Decoding Whoop’s stress metrics calculation
Previously, users could only view the value for the stress metric on an individual daily basis. This was a step in understanding one’s stress levels, but it was just the tip of the iceberg. For example, there was no option to view stress trends. With this update the company is allowing users to delve much deeper into the nuances of their daily stress.
Whoop’s approach to stress metrics is rooted in scientific data and user-centric design. At the heart of its calculations are two vital physiological indicators: Heart Rate Variability (HRV) and Heart Rate.
- HRV: measures the variation in time between each heartbeat. It’s a key indicator of the body’s stress response. A higher HRV suggests a relaxed state. A lower HRV, on the other hand, can indicate stress or fatigue.
- Heart rate: A consistently elevated heart rate, especially when at rest, can be a sign of increased stress levels.
The stress monitor analyzes these two metrics in real-time. For instance, if a user’s heart rate is higher than usual and their HRV is lower than usual, the algorithm interprets this as a sign of stress.
But Whoop doesn’t just look at real-time data. The app compares the collected data to the previous 14 days, establishing a baseline to better assess fluctuations in values. This historical context is crucial. By understanding a user’s typical resting heart rate and average HRV, Whoop can more accurately determine if current readings are a cause for concern.
Physical activity naturally affects heart rate and HRV. Recognizing this, Whoop has designed its software to differentiate between stress caused by exercise and other types of stress. When users log physical activities such as running or biking, the app adjusts the stress levels based on the intensity of the workout. This ensures that the stress metrics aren’t skewed by physical exertion.
To make the data easily digestible for users, Whoop’s stress monitor assigns a value ranging from 0 to 3. Higher values indicate increased stress levels. This simplified scale allows users to quickly gauge their stress levels at a glance.
A deeper dive into daily stress
This latest software update allows for a much deeper dive into daily stress. Users can now see “Total Day Stress,” “Non Activity Stress,” and “Sleep Stress”.
Whoop’s introduction of these detailed stress metrics is not just about data. It’s about empowering users to take charge of their mental and physical health. By providing insights into different aspects of daily stress, Whoop is equipping its users with the tools they need to lead more balanced and healthier lives.
Total Day Stress: The bigger picture
The “Total Day Stress” metric provides an overarching view of a user’s stress throughout the entire day. This includes stress from physical activities, work-related stress, and even the minor stressors that we often overlook. By offering a holistic view, users can better understand the peaks and troughs of their stress levels as the day progresses.
Non-activity Stress: Beyond physical exertion
While physical activity is a known contributor to daily stress, it’s not the only factor. “Non Activity Stress” focuses on the stress that arises outside of physical activities. This could be due to work pressures, personal issues, or even environmental factors. We also have this influence, some more than others depending on their circumstances. By isolating the metric, Whoop provides clarity on how daily life, minus the workouts, impacts our well-being.
If you find non-activity stress elevated, some breathing exercises might fit the bill. There’s a section in the smartphone app for that.
Sleep Stress: The silent disruptor
Sleep is crucial for recovery and overall health. However, stress can significantly impact the quality of our sleep. The “Sleep Stress” metric sheds light on the stress levels experienced during the night. Whether it’s due to nightmares, restless sleep, or other factors, understanding sleep stress can be pivotal in improving overall sleep quality.
Trends: The power of data over time
Another feature of this update is the ability to view trends. Now you can view long-term changes in your stress metrics, just like you can with any other Whoop data.
As can be seen from the above screenshots, instead of just daily snapshots, you can now see how their stress levels fluctuate over days, weeks, or even months. This trend data can be invaluable in identifying patterns, understanding triggers, and ultimately, making informed decisions to manage and reduce stress.
